Have a huge problem to solve the decoding of manchester-code
for our radiomodem with 8051 microcontroller. Atmel..!!

The encoding i've solved, as i think, in a smart way with Timer0.
Easy to change the bit-rate.
There are no problems sample the received signals,
but how do I handle the calculations with controlled sample.

The radiomodems leavs always a nois with a lots of bits in
different rate, but I'm only interested of decoding the
'right signals'. It's 8 synk-bits, start and stop-bits.
There is also a little bit fading who fluctuate the dutycycles.
The rate for the tranfer is between 4800 and 9600 bit/s

If I could read the manchester-codes, there is no problems
for me to solve the translating of memorized manchester
to normal characters.

But for me the calculations in assembler is very difficult-
I don't now how to do. - biterror, bitsynk bla bla...!!!???

Can anyone give me some advice
